Both offer a different sound. Go read reviews of each speaker and you will find out for yourself. The B&W speakers in general do not sound good with poor equipment. They need high current amps to make them sing, more so with the matrix series. The midrange and high frequencies are the key areas you want to note so once you read the reviews, you will know which one you prefer, if you are not going to bring them home to compare which I think you should do.
